建筑硫磺类防腐蚀工程包括用硫磺胶泥或硫磺砂桨浇筑的防腐块材面层及硫磺混凝土。硫磺掺入增韧剂和耐酸粉料即成硫磺胶泥,再加入耐酸细骨料即成硫磺砂浆,将硫磺胶泥(或砂浆)注入粗骨料的空隙中即成硫磺混凝土。由于采用热法施工,故具有快凝的特点,对硝酸、硫酸、盐酸、磷酸等均有抗腐蚀能力,特别是在对硝酸的抗腐蚀措施中,它和水玻璃类材料并列为两大支系。1976年已正式纳入《建筑防腐蚀工程施工及验收规范》(TJ212—76,以下简称规范)。我们在使用这种材料时发现了一些问题,现
Construction sulfur corrosion protection projects include the use of sulphur cement or sulphur sand padding of anti-corrosion blocks and sulphur concrete. Sulfur is added into the toughening agent and the acid-resistant powder is the sulfur cement, then the acid-resistant fine aggregate is prepared into the sulfur mortar, and the sulfur cement (or mortar) is injected into the voids of the coarse aggregate to form the sulfur concrete. Due to the thermal method, it has the characteristics of rapid solidification, and it has corrosion resistance to nitric acid, sulfuric acid, hydrochloric acid, phosphoric acid, etc. Especially in the anti-corrosion measures for nitric acid, it is listed as two major branches of water glass material. system. In 1976, it was formally incorporated into the “Code for the Construction and Acceptance of Building Anti-corrosion Projects” (TJ212-76, hereinafter referred to as the Code). We found some problems when using this material.
